El Chapo’s cocaine submarine revealed

Jurors in drug kingpin Joaquin "El Chapo" Guzman's American trial have been shown footage of the first-ever US Coast Guard interception of a cocaine-packed submarine.

Coast Guard Lieutenant Commander Todd Bagetis, who took part in the September 2008 seizure, said his crew had been patrolling international waters when they came across the semi-submersible, some 563 kilometres east of Guatemala, the New York Post reports.

Using night-vision goggles, his team boarded the submarine - where an irate crew immediately tried to sink the boat and throw the officers overboard.

The dark footage shows a single head popping up from the hatch, and then water flooding the vessel. Mr Bagetis had earlier testified that the boats were designed to sink in as little as three to five minutes if desired.

Once they had detained the crew, Mr Bagetis said his team discovered 237 bales of cocaine - about 5896 kilograms.
